Formula & How Gear Ratio & RPM Calculator Works
Speed reduction occurs when driven gear is larger than driver gear, increasing torque proportionally.
- Enter Driver Gear Teeth (Input): Input your target parameter value.
- Enter Driven Gear Teeth (Output): Input your target parameter value.
- Enter Input Motor Speed (RPM): Input your target parameter value.
- Apply Formula: Calculate using
Gear Ratio = Teeth (Driven) / Teeth (Driver). - Review Results: View exact computed answers, metrics, and worked mathematical proofs.
